Basic Rules of Network Logic Rule 1. Before an activity may begin, all activities preceding it must be completed. (Activities with no predecessors are self-actuating when the project begins.) Rule 2. Arrows imply logical precedence only. Neither the length of the arrow nor its “compass” direction on the drawing have any significance. (An exception to this rule is discussed under “Time-scaled Networks”.)

Basic Rules of Network Logic (cont.) Rule 3. Event numbers must not be duplicated in a network. Rule 4. Any two events may be directly connected by more than one activity. Rule 5. Networks may have only one initial event (with no predecessor) and only one terminal event (with no successor).
